(Richmond, IN)--There have been multiple drug overdose calls in Richmond on Thursday and Friday morning. Overdoses have occurred on South 6th, South 13th, and Irish Hills Court. One case, though, demonstrates how addictive drugs can be. A Centerville woman overdosed at a Richmond home at 8 o’clock Thursday night. She had to be revived with Narcan. Then, just four hours later, she went to a different home and overdosed again. First responders were again able to revive her at just after midnight Friday morning. One county official said that a dangerous batch of heroin may have infiltrated the area.
